Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing, to this reality
It is further elaborated with new.It should be appreciated that specific embodiment described herein is only to explain this practicality
It is new, it is not used to limit this utility model.
Embodiment：As shown in Figures 1 to 5, a kind of pilot operated directional control valve integrating device, including valve block 1, sets in the valve block 1
There are the first hydraulic control one-way valve 2a, the second hydraulic control one-way valve 2b, first throttle valve 11a, second throttle 11b, the first reversal valve 12
With the second reversal valve 13；Commutation push rod 6, commutation valve pocket 7 and reversing valve core I 8 are provided with inside first reversal valve 12, it is described to change
To push rod 6 located at the top of the commutation valve pocket 7, the reversing valve core I 8 is in the endoporus of the commutation valve pocket 7；Described
Two reversal valves 13 include second spring 9 and reversing valve core II 10, and the reversing valve core II 10 is located under the second spring 9
Side, the B mouths of the top valve pocket of first reversal valve 12 by oil circuit with second reversal valve 13 are connected, and described first changes
It is connected to the bottom valve pocket of the bottom valve pocket by oil circuit with second reversal valve 13 of valve 12, second reversal valve 13
A mouth of the bottom valve pocket by oil circuit with second reversal valve 13 is connected.
Preferably, a diameter of Φ 2mm of the reversing valve core I 8.
Preferably, first throttle valve 11a includes the first spring 3, throttling valve core 4 and throttle valve plate 5, described first
